I FRANK HUMPHREVILLE, OF ATLANTIC CITY, NEW JERSEY.

OIL BURNER.

Application filed June 16, 1923. Serial No. 645,854

To all whom it may concern.

Be it knownthat I, FRANK HUMPHREVILLE, a citizen of the United States, and a resident of Atlantic City, in the county of Atlantic and State of N ew Jersey, have invented a new and Improved Oil Burner, of which the following is a full, clear, and exact description.

The present invention relates to new and useful improvements in burners and pertains more particularly to burners of the oil and air type.

It is one of the objects of the'present invention to provide a burner for mixing oil and air and igniting the same to form a flame.

It is a further object of the invention toprovide aburner which is adapted for use in connection with either'acooking stove or a heating stove or boiler.

It is a further object of the invention to provide means for adjusting the flow of oil to the burner.

It is a. further object of the inventionto providenieans for cutting off the burner,

which means comprises a pair of valves operated together in" such a manner that they are either open 'or closed simultaneously.

It is a further object of the invention to so construct the burner that the rate of'supply' of oil may be varied in order that the best operating results maybe had with oils of various grades.

It is astill further obj eot of the invention toso construct the burner that the flame may be varied in such a manner that either a wide short flame or a narrow long flame may be had.

With the above and other objects in. View,

the control elements of the burner.

l/Vith reference to Figure 3, it will be noted that the compartment 10 is provided Figure 2 is a view in rear elevation thereof is adapted to contain the burner per se and the compartment 11 is adapted to contain with an open forward end, thelower portion of which is inclined as at 12, and has an upwardly turned lower wall 13. This lower wall 13 serves to direct the fuel to the discharge'opening 14 of the compartment 10 in case the fuel supply is left on, and leading from said discharge opening 14 there is a drain pipe 15. This drain pipe 15 is connected to an overflow tank, not forming a part of the present invention and, there fore, not illustrated'herein, I I

The rear-end of this compartment 10' is open, as illustrated by the reference character .16, and said open end provides means r:

for permitting air to enter the compartment 10 in order to promote combustion therein during the operationof the burner. Mounted in this compartment 10 are-two members 17 and 18, the member 17 constituting an oil or fuel supply and the member 18 constituting an air supply. The memberv 17 has a discharge opening 19, the upper wall of said member 17 being'bent downwardly, as indicated by the reference character 20, and formed with aprojecting lip 21. The lower wall of the-opening is turnedIdo-wnwardly, as at 22, and serves to direct the fuel passing through the member 17 downwardly, for a purpose to be hereinafter described. v a j The rearend of each of these members 17 and 18 is provided with a clean-out plug 23, by means of which accessmay be had to the interior of either member.

The forward end of the member 18' is closed except for a relatively small dis-- charge opening24. The upper wall of the member 18 is provided on its exterior with a guide 25 and mounted insaid guide 25 is an air spreader 26. This air spreader 26 has its rear end open and its bottom wall 27 is inclined, as shown. Projecting from the spreader 26 is an "extension 28 adapted to be received within the guide 25 and forming means by. which the air spreader 26. is ad- Les justable with relation to the opening 2 1 in the forward end of the member 18. This air spreader 26 is providedwith a. discharge 0 enin 29 and said dischar e 0 enin is p b b b so arranged with relation to the spreader 26 that it will occupy a position below the discharge opening of the member 17.

The member 17 is provided at its rear end with a coupling 30 and branching from said coupling, preferably at right angles to the member 17,. is a pipe 31. This pipe 31 is connected to a valve 32, which valve is adapted to open or close the passage to the member 17. Leading from the valve 32 is a short section 33 of pipe and connected to this shortsection 33 is a. valve 34, to the opposite side of which is connected. a pipe 35. This pipe 35 is connected to a fuel or oil reservoir, not shown.

The member 18 is provided witha coupling 36 and leading from said coupling 36. is a pipe 37', which is connected to a valve 38, and leading from said valve 38 is a pipe 39 which is connected to a suitable source of compressed air supply, not shown. In order to prevent movement of the valves 32 and 38 in a rotary direction or relative to the pipes to which they are connected, one of said valves is provided with a lug 40 which occupies or fills the space between the valve members where they are attached to their respective pipes 35 and 39.

The reference character 41 designates the valve stem of the valve 32 and the reference character 42' designates the valve stem of the valve 38. The valve stem 41 is provided with a lug 43 and carried by the valve stem 41 is an arcuate gear member 44 having a slot to receive the lug 43 in such a manner that the arcuate gear member 44 is caused to turn with the valve stem 41.

Carried by the valve stem 42 in such a manneras to rotate therewith is an arcuate gear member 45 and said arcuate gear member 45 meshes with the arcuate gear member 44 in such amanner that as the arcuate gear member 44 is rotated ineither direction, a simultaneous rotation ofthe arcuate gear member 45 willbe had. Carried by the arcuate gear member 44 is an operating member 46 which projects through a slot 47 in the rear wall 48' of the compartment 11 and provides'meansby which the arcuate member 44 is operated.

The reference character 49 designates the valve stem of the valve 34 and connected to said valve stem 49 is a lever 50, which lever has an operating member 51. project'- ing through a slot 52 in the rear wall 48 of the compartment 11. This member 51 forms the means by which the lever50 is operated to rotate the valve stem 49.

As shown by dotted lines in Figure 4 and full lines in Figure l, a pair of eccentric members 53 and 54 are secured by set screws 55 and 56 respectively on. the inner face of the rear wall 48 of the compartment 11, and these eccentric members 53 and 54 are adaptedto form stops to limit. the swinging movement of the lever 50.

The device operates inthe following manner. The burner is adapted forattachment toa stove or furnace by cutting an opening, preferably in the door thereof, of a size to receive the forward end of the compartment 10. After the device hasbeen installed, the pipe 35 is connected to the fuel supply the pipe 39 is connected to the air supply, and the pipe 15 is connected to the overflow tank. After this has been done, the fire compartment of the stove or boiler to which the:

burner is attached, is filled with paper. or

other inflammable material. The-two valves I 32 and 38 are now moved to open. positiom.

after which the lever 50 is operated to open the valve 34 by moving the same to the left in Figure 4,. towardsthe end of the slot 52 marked High. The movement of the lever 50 is carried. out slowly until the proper amount offoil. is admitted. to; make a short flame. After this has been done, the eccentric member 54 is turned until it moves into engagement withthelever 50, in. which position it is secured by means of a set screw 56. lVith the parts in this position it will be seen that an adjustment for a low flameis made.

After this has been done, the lever. 50

is moved still further towards the. end. of,

the slot designated High until enough Oil is admitted to the burner to bur-n a high flame. lVhen the sufficient flame has been obtained, the eccentric'member 53 is moved until it engages the lever 50, and is secured in this position by means of" its set screw 55.

After this has been done,.i.t will be-seen1 that the lever 50 may be moved until it engages either of the eccentric members 53" or 54' when either a high or low flame may be obtained dependent upon the eccentric member with which the lever 50 contacts,

Between these two extremes, the flamemay be adjusted by positioning. the lever. 50' at any point between the two eccentric members 53 and 54. It is to be understood that in order to obtain the flame, the paper or otherinflammable material within the stove or heater has been ignited before the. adjustments were made, and it is to be] also understood that a regulator in the form. of a. valve is employed adjacent the air supply to regulate or determine the volume of air fuel or air cannot becut off singly, which is a common practice where two independent valves are employed, since by cutting ofi either valve the burner ceases to function and the operator is very likely to forget to turn off the other valve.

In order to determine the character of the flame, the air spreader 26 is adjustable relative to the member 18, as heretofore From the foregoing it is apparent that the present invention provides a new and improved burner of the oil and air type, in which means is provided whereby when the supply of either the oil or air is out off,

' the supply of both is automatically cut off.

Furthermore, the invention provides for independently regulating the flow of oil, thus providing a burner capable of use with fuel oils of various grades and weights.

Furthermore, the invention provides means whereby the valve controlling the supply of fuel particularly may be maintained in adjusted position so long as one grade of oil is employed.

While the burner is in operation, the air supplied by the member 18 will cause a drain of air through the compartment 10 and said drain of air aids in supporting proper combustion of'the flame at the flame end of the burner. The heat present adjacent the burner also aids in maintaining this drain of air through the compartment 10 and by thisconstruction a more perfect combustion of the fuels is had.

Having thus described the invention, what is claimed is: v 5 1. In a fuel burner of the type described,

an air nozzle, an oil nozzle, means for 1 simultaneously controlling the flow of air and oil to said air and oil nozzles, means for limiting the movement of said last-,

mentioned means, means for controlling the J volume ofoil flowing to the oil nozzle, said last-mentioned means comprising a valve I arranged between the first-mentioned means and the oil supply, a lever for operating said valve, and adjustable means adapted for engagement with opposite sides of said lever to limit the movement thereof.

2. In a fuel burner of the type described, an air nozzle, an oil nozzle, means for simultaneously controlling the flow of air and oil to said air and oil nozzles, means for limiting ,the movement of said last-mentioned means, means for controlling the volume of oil flowing to the oil nozzle, said last-mentioned means comprising a valve arranged between the first-mentioned means and the oil supply, a lever for operating said valve, and an eccentric member mounted on each side of said lever and adapted to engage its respective side of the lever to limit movement of the lever in the direction of the eccentric.
